Product Description:
The MKE118D-012-CP3-KE6 is a servo motor for hazardous areas produced by Bosch Rexroth Indramat within the MKE Synchronous Motors series. Its flameproof housing meets ATEX requirements and supports safe operation in zones where explosive atmospheres may be present. The motor provides closed-loop rotary motion for industrial automation drives and positioning axes while operating in ambient temperatures from 0 to +40 °C. Power and feedback conductors enter through a terminal box mounted on the top of the frame, and the cable entry accepts diameters from 17.0 mm to 19.5 mm. This arrangement keeps the electrical connections grouped in one protected location on the motor.
Under a 60 K winding temperature rise, the motor supplies a continuous torque of 48.0 Nm while drawing 13.0 A. For short duty cycles, it can reach 187.0 Nm of torque and a peak phase current of 58.5 A. A torque constant of 4.29 Nm/A and a back-EMF constant of 263.5 V per 1000 rpm give the drive predictable motor behavior during sizing and control. The rated winding set labeled 012 has an inductance of 15.000 mH and a resistance of 0.98 Ω, while an internal discharge capacity of 20.2 nF helps reduce common-mode noise. The optical multi-turn absolute Hiperface encoder, model M1, provides 128 increments per revolution and supports speed regulation up to 2000 rpm without loss of resolution.
An integral holding brake provides 70 Nm of locking torque to hold vertical loads when power is removed. The shaft has a DIN 6885 keyway and a shaft seal, while the enclosure carries an IP 65 rating and Class F insulation for thermal endurance. Motion response is affected by a rotor moment of inertia of 0.03620 kg·m², which supports controlled acceleration and deceleration through the connected drive. Operating noise is limited to 61.1 dB(A) ±3, and the assembled unit weighs 65.0 kg. These values are useful when planning machine acoustics and support capacity around the installed motor.
